I would suggest that all ambiguities are resolved by example. In this case, the following would seem to apply:

4824: 4 Ort, because in place of the first digit the words Torf, fort, Tor could be used

I read that to say, that as 'aaa' can be applied at the first step, inserting a digit at that point is illegal. Therefore your example has no solutions.

    BrowserUk,
    I also read the rules incorrectly because of the following example:
    04824: 0 Torf 04824: 0 fort 04824: 0 Tor 4
    The last solution is what lead me astray. If it had read:

    As you work left to right, if at any point a word can be inserted - using a digit is illegal and at no point can two digits be adjacent

    I would have understood much better. In any event, my solution is buggy and produces incorrect results. Since it seems like you were after approaches, I believe mine is interesting because of the unrestricted integer partitions. I have no interest at this point in making it a correct solution.

    Cheers - L~R

    Nope, that doesn't do it, because using Torf ,fort, or Tor 4 produces a solution. My doubt is whether a digit can be inserted where there could be a word, but not one that produces a solution.

    I haven't rigorously examined the sample solutions for lack of one that would establish the point, nor do I really care to.

      My doubt is whether a digit can be inserted where there could be a word, but not one that produces a solution.

      Well. I think it is perfectly clear. You cannot use a digit at any point where a word is available. (*)

      (*) I was about to add 'regardless of whether a solution can be achieved', but it is unnecessary. If there is a word available, you cannot ignore that word and use a digit. For any reason, including achieving a solution that would otherwise be complient.

      For the record, without that rule, there would be many more solutions that are presented in the official results.

        Well, you've rewritten the requirement to avoid the problematic "can", but that you did so, rather than argue that "can" is not ambiguous, just shows that "can" is unambiguously ambiguous :)

        Would the sample provided in the spec have any additional solutions? If not, this falls into the category of ambiguities remaining after "all ambiguities" are resolved by the sample.
